I have enjoy working on out-of-the-ordinary projects ever since I was little. From building go carts and boats when I was in junior high, designing and building computers in the seventies, and recently restoring boats, cars and airplanes, I've taken the path less traveled. Because of my love of odd projects, my long suffering wife of 45 years has coined the phase. "Life with David". Now that I'm retired I can spend much more time on these hobbies. So join me as I explore a wide range of interests.
The problem that come with most every convenience we buy (like the cushy adjustable chair) is the question we should ask before we buy. The question is "What is the PIA factor" with the product. "PIA" ? > Pain In The Ass, that come with virtually everything! that is What is the failure rate and the complexity of the repair? Quite frankly, the manufacturers build to fail. And because people generally don't have the patience or facility or the time to fix crap any more.
Great overview, thanks. I am still holding off a bit until Adafruit (or others) have released convenient High Speed Transmit (HSTX) peripherals to play around with DVI. Not many examples on the topic out there yet, it seems.
LOL. I think it would be close with the Pentium winning in the memory department. Power is another thing... 15 Watts for the Pentium CPU alone, milliwatts for the entire Pico 2. Enjoyed hearing from you again!
Nice video. 👍 I saw in somebody else's RP2350 video that VSCode's compiler does a very poor job by default, but with a little tuning the RISC-V cores come in line with the performance of the M33 cores..
@@LifewithDavid1 idk, considering the only way you could get the code to compile and the pico to receive it was to basically nuke your system, that doesn't sound like a you issue lol something was interfering.
I was pretty sloppy where I installed the previous applications for the RO2040. Remember there was no "recommended" installer for Windows machines. I have problems (my own irrational need) in not knowing exactly how something works. So I'm a little uncomfortable that VS Code does it all. But that's just me. Thanks for your comment.
@@LifewithDavid1 There's an errata which covers it, but in short one stepping has a tiny leakage issue which is unlikely to matter to anybody who isn't trying to use the RP2350 as a logic analyzer with floating leads. If the inputs are driven by another device there is no issue. If the inputs are floating, the programmable pull-downs aren't strong enough to pull some of the lines to a zero so the RP people recommend adding a pulldown resistor to help which of course burns current.
Looking forward to watching all the previous bare metal episodes, as I have more time on my hands, I can have a go myself. Really enjoy all your videos David. Thanks for sharing
OMG. I was about to replace my chair, but didn't really want to because it's very comfortable. I came here looking for how easy it was to change the cylinder, but found this video a few days ago, tried it and so far it seems to have done the job!!! Amazing!!
I would have liked it very much if you showed the way that you pressure tested the pump before you put it back into the water and more detail on exactly how you tested the current on the pump . Otherwise, it's an excellent thums up !!!
Thanks! I'm sorry I didn't give more info on the pressure test. It's hard when you are actually doing the repairs to get all the details on video. I had low pressure air (about 5 psi), that I introduced into the switch housing through the pressure test hole. Then I sprayed soapy water around the gaskets to see if any bubble appeared. They didn't; so I decided everything was good. I didn't test the current of the running pump; just the resistance. Thanks for your comment!
Amazing. Thanks David. In the least, I will have our mechanic look at our plane. I think we're over-inflated on the mains. This is also problematic for fuelling to the 18 gallon tabs. Sometimes we believe we are filled to 18 and then once we're parked, the Cherokee is settling in a different pitch. Suddenly we have 16 gallons fuel. Not sure which is correct yet but the aircraft should be level when fuelling in the least.
Try my other easier fix first. The link is in the description and also pinned to the top of the comments. You may not need to disassemble at all. I would not use olive oil, it would get sticky. I don't think it is comparable with the seals. Good luck!
So glad I watched this video. Turning the chair upside down worked! I really wasn’t too excited about a trip to the hardware store for a pipe clamp or length of pvc pipe or using the chair in it’s lowest position. Thanks so much for explaining and sharing. From a 70+ old lady!
I'm sorry, but I haven't tried that. I think it would take me quite a bit of research and experimentation to figure that on out. I do more with DMA with my AWG videos; maybe that will give you some ideas. I even do some bare metal DMA in one of my recent vids. Good luck.
hello sir david i have the same problem on my dso hantek 2d10. i have searched in eev blog not find firmware file like the one you have maybe in forum has been deleted, i have difficulty in recovering my dso, would you please share with me the file you used to recover my dso.? 
I just checked and the link I posted in the description to the David Alfa's EEV blog still works. I think you should get all the help you need there. Good luck!
Try my other, easier fix first! The link is pinned to the top of the comments. All the hydraulic fluid you need may already be in the cylinder. I would stay away from any oil that could soften the seals that are used in the cylinder. Good luck.
I live on America's North Coast, Cleveland, Ohio. We have to turn the power on to the outdoor unit for a while before we can actually start the compressor. There is a heater in the compressor to prevent fluid lock during cold spells. The blanket keeps that heat in.
Believe it or not...when I was preparing to camp at AirVenture the first time, there was a great blog on how to shower there which helped me a lot. The next year; it had disappeared from the internet. I felt I had to pass that info to new campers. Since I don't do blogs; this is what you've got. Thanks for watching!
Lol I love how he is sinking the who time at the start. I am going to us a pvc pipe sliced with a hose clamp on it. It will keep my chair up where I need it.
You should have shown testing the original capacitor too. Speaker caps aren't all that prone to failure as they don't run at elevated temps like power supply parts. Also if you are going through the motions of swapping the capacitor, a film cap if you can fit it in makes so much more sense than a non-polar electrolytic.
I took the simpler route. When the boss was out of the office I wrapped the cylinder in a spiral of corrugated cardboard an packing tape. Otherwise I would get yelled at that there is no budget for chairs and get back to work!
You might try the ideas in my jump video (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qegs8LGINww.html). Set up a countdown loop and output the value when you see a rising edge. Good luck!
Hi David, it's so great you took the effort to take a video of this process. That's exactly what I was looking for. Great stuff and well explained! Best regards Nils
